Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761212, here are decompositions:

43 + 8761169 = 8761212
59 + 8761153 = 8761212
71 + 8761141 = 8761212
73 + 8761139 = 8761212
79 + 8761133 = 8761212
113 + 8761099 = 8761212
193 + 8761019 = 8761212
311 + 8760901 = 8761212

Showing the first eight; more decompositions exist.
